How can I provide unlimited free downloads?

However, you don't actually need any special "download service" like E-junkie if you aren't selling your download and don't need to restrict access to paying buyers only. Here's some ideas to provide free downloads that don't require E-junkie:

If you just want people to download a file for free and don't need to issue each person a unique link that expires, then you can just upload the file to your Web site or any dedicated free file hosting service and make a link to it, just like you'd make a link from one page to another:

If you at least want to collect names/emails, but you still don't need to issue each person a unique link that expires, you could have a generic HTML contact form on your site that submits to any generic form-handler script -- or even a subscription form for a mailing-list service like Aweber, MailChimp or GetResponse (all of which can also be integrated with your E-junkie sales) -- which then leads to your free-download page after the form is submitted.
